Introduction
History

TPEG technology was originally proposed by the European Broadcasting Union (EBU) Broadcast

Management Committee, who established the B/TPEG project group in the autumn of 1997 with a brief

to develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information

in the multimedia environment. TPEG technology, its applications and service features were designed

to enable travel-related messages to be coded, decoded, filtered and understood by humans (visually

and/or audibly in the user’s language) and by agent systems. Originally, a byte-oriented data stream

format, which may be carried on almost any digital bearer with an appropriate adaptation layer,

was developed. Hierarchically structured TPEG messages from service providers to end-users were

designed to transfer information from the service provider database to an end-user’s equipment.

One year later, in December 1998, the B/TPEG group produced its first EBU specifications. Two

documents were released. Part 2 (TPEG-SSF, which became ISO/TS 18234-2) described the syntax,

semantics and framing structure, which was used for all TPEG applications. Meanwhile, Part 4 (TPEG-

RTM, which became ISO/TS 18234-4) described the first application for road traffic messages.

Subsequently, in March 1999, CEN/TC 278, in conjunction with ISO/TC 204, established a group

comprising members of the former EBU B/TPEG and this working group continued development work.

Further parts were developed to make the initial set of four parts, enabling the implementation of a

consistent service. Part 3 (TPEG-SNI, ISO/TS 18234-3) described the service and network information

application used by all service implementations to ensure appropriate referencing from one service

source to another.

Part 1 (TPEG-INV, ISO/TS 18234-1) completed the series by describing the other parts and their

relationship; it also contained the application IDs used within the other parts. Additionally, Part 5, the

public transport information application (TPEG-PTI, ISO/TS 18234-5), was developed. The so-called

TPEG-LOC location referencing method, which enabled both map-based TPEG-decoders and non-map-

based ones to deliver either map-based location referencing or human readable text information,

was issued as ISO/TS 18234-6 to be used in association with the other applications of parts of the

ISO/TS 18234 series to provide location referencing.
The ISO/TS 18234 series has become known as TPEG Generation 1.
TPEG Generation 2

When the Traveller Information Services Association (TISA), derived from former forums, was

inaugurated in December 2007, TPEG development was taken over by TISA and continued in the TPEG

applications working group.

It was about this time that the (then) new Unified Modelling Language (UML) was seen as having major

advantages for the development of new TPEG applications in communities who would not necessarily

have binary physical format skills required to extend the original TPEG TS work. It was also realized

that the XML format for TPEG described within the ISO/TS 24530 series (now superseded) had a greater

significance than previously foreseen, especially in the content-generation segment and that keeping

two physical formats in synchronism, in different standards series, would be rather difficult.

As a result, TISA set about the development of a new TPEG structure that would be UML-based. This has

subsequently become known as TPEG Generation 2.

TPEG2 is embodied in the ISO/TS 21219 series and it comprises many parts that cover introduction,

rules, toolkit and application components. TPEG2 is built around UML modelling and has a core of

rules that contain the modelling strategy covered in ISO 21219-2, ISO 21219-3 and ISO 21219-4 and

the conversion to two current physical formats: binary and XML; others could be added in the future.

TISA uses an automated tool to convert from the agreed UML model XMI file directly into an MS Word

document file, to minimize drafting errors, that forms the annex for each physical format.

ISO/DIS 21219-9:2020(E)

TPEG2 has a three-container conceptual structure: message management (ISO 21219-6), application

(several parts) and location referencing (ISO/TS 21219-7). This structure has flexible capability and

can accommodate many differing use cases that have been proposed within the TTI sector and wider

for hierarchical message content.

TPEG2 also has many location referencing options as required by the service provider community, any

of which may be delivered by vectoring data included in the location referencing container.

The following classification provides a helpful grouping of the different TPEG2 parts according to their

intended purpose. Note that the list below may be incomplete, e.g. new TPEG2 parts may be introduced

after publication of this document.

— Toolkit parts: TPEG2-INV (ISO/TS 21219-1), TPEG2-UML (ISO 21219-2), TPEG2-UBCR (ISO 21219-3),

TPEG2-UXCR (ISO 21219-4), TPEG2-SFW (ISO 21219-5), TPEG2-MMC (ISO 21219-6), TPEG2-LRC

(ISO/TS 21219-7).

— Special applications: TPEG2-SNI (ISO/TS 21219-9), TPEG2-CAI (ISO/TS 21219-10), TPEG2-LTE

(ISO/TS 21219-24).

— Location referencing: TPEG2-OLR (ISO/TS 21219-22), TPEG2-GLR (ISO/TS 21219-21), TPEG2-TLR

(ISO 17572-2), TPEG2-DLR (ISO 17572-3).

— Applications: TPEG2-PKI (ISO/TS 21219-14), TPEG2-TEC (ISO/TS 21219-15), TPEG2-FPI

(ISO/TS 21219-16), TPEG2-TFP (ISO 21219-18), TPEG2-WEA (ISO/TS 21219-19), TPEG2-RMR

(ISO/TS 21219-23), TPEG2-EMI (ISO/TS 21219-25), TPEG2-VLI (ISO/TS 21219-26).

TPEG2 has been developed to be broadly (but not totally) backward compatible with TPEG1 to assist

in transitions from earlier implementations, while not hindering the TPEG2 innovative approach and

being able to support many new features, such as dealing with applications having both long-term,

unchanging content and highly dynamic content, such as parking information.

This Technical Specification is based on the TISA specification technical/editorial version reference:

SP20009_3.3_001.The International Organization for Standardization (ISO) (and/or) International

Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with

this Technical Specification may involve the use of a patent concerning “the HD Radio Bearer and

Linkage Information” given in 8.24 and other sections of this document. ISO [and/or] IEC take[s] no

position concerning the evidence, validity and scope of this patent right.

The holder of this patent right has ensured the ISO (and/or) IEC that he/she is willing to negotiate

licences under reasonable and non-discriminatory terms and conditions with applicants throughout

the world. In this respect, the statement of the holder of this patent right is registered with ISO (and/or)

IEC. Information may be obtained from the following.

DRAFT INTERNATIONAL STANDARD ISO/DIS 21219-9:2020(E)
Intelligent transport systems — Traffic and travel
information (TTI) via transport protocol experts group,
generation 2 (TPEG2) —
Part 9:
Service and network information (TPEG2-SNI)
1 Scope

This part of ISO 21219 establishes the method of delivering service and network information within

a TPEG service. The TPEG-SNI application is designed to allow the efficient and language independent

delivery of information about the availability of the same service on another bearer channel or similar

service data from another service provider, directly from service provider to end-users.

NOTE A number of tables of information are described, which provide comprehensive options for describing

services, their timing, content, geographical coverage, etc. In all TPEG streams, it is mandatory to deliver to so-

called GST. Additionally, it is possible to signal linkage of content between different bearers and services.
